- The Chequamegon-Nicolet National Forest still needs more time before it can open its trails and campgrounds. The heavy snowfall and long winter delayed the openings earlier this spring. Now forestry officials says they still need more time to keep an eye on conditions of some of the 53 developed campgrounds. Some sites are open though. In the Northwoods, Lakewood-Laona Ranger District campgrounds and trails are open. Eagle River- Florence Ranger District trails are also open as of yesterday.
